' couPoN- SHEARS.

SPECIFICATION forming part of Letters Patent No. 274,998, dated April 3, 1883. Application tiled November 16, 1882. (No model.)

connected with its bonds. 1n one kind ot' these a pair of shears with the blades nlade somewhat longer than usualhas had the ends bent at right angles with the main portions of the blades, so that when one side has been progressivelysevered,as in the ordinary shearing action ot' a pair ot' shears, theother side is then also attempted to be cut along its lull lengt-h at once bythe further operation of the instrument. In another a supplementary blade is hung on apivot at right angles to theordinary blade, by which it is worked with the shearing motion that is necessary for its eicient action.

Theobject of thepreseut invention isto combine the simplicity' of one of these kinds ot' instruments with the efficiency ot' the other, and it `is accomplished by having the blades turned at" right angles, and with the cutting-edges of the end pieces in angular planes relatively to those of the ncrmalshears and with each other, so thatthe shearing action of both sets ofblades will be simultaneous or continuous and progressive.`

'lo enable othersskilled in the arts to which it appertains to make and use my invention, I will proceed to describe its construction andyoperation with reference to the drawing.

The figure represents a duplex or double- 4o acting shears made according to my said improvement, and opened so that its parts and peculiar construction may be more fully eX hibited.

The upper blade, c, has secured to it at a right angle the angular blade b, so that as those blades close upon the lower blades,c and d, the two sides of the intervening couponl are cut together and simultaneously from and to their point of intersection. The lower blades, it' 5o made integral, may be sharpened readily on the exterior surface ot the angle; but by maltiug the upper blade, b, separate from a they may be disconnected and sharpened separately without the difficulty that would be inherent to sharpening them together on the interior ot' the angle. Both the end blades rare represented in the drawingas secured to the main blades by screws that are tapped into their ends. 6o

I claim as my invention and desire to secure by Letters Patent- The combination, with the cutting-blades a and c, ot' the cutters b and d, secured rigidly at right angles therewith, and with relatively angular cutting-edges to cnt with a shearing motion, substantially as described.
